350W Ultra-thin AC/DC Enclosed Switching power supply - LMF350-23BxxUH

LMF350-23BxxUH series is one of Mornsun’s fanless semi-potted AC DC enclosed power supplies, which is suitable for industrial and outdoor occasions where the environment is relatively harsh. It features a universal AC input voltage range, accepts AC or DC input voltage, is cost-effective, has high PF value, high efficiency, high reliability, and has safety insulation.

 

These converters offer excellent EMC performance and meet EN/UL62368, EN61558, EN60335, and GB4943 standards, which can be widely used in areas of industrial, lighting, electricity, security, telecommunications, smart home, etc.

 

Advantages of LMF350-23BxxUH series AC/DC enclosed power supplies

Wide applied range

a. Universal input voltage range: 85-305VAC

b. Operating temperature range: -40℃ to +85℃

c. Side mounting is available

d. Meets EN/UL62368, EN61558, EN60335, GB4943 standards

e. PF>0.95 (Full load at 230VAC)

 

High reliability

a.  Adopting the fanless design to improve the reliability of the power supply in dusty and other harsh environments can effectively prevent failure because of inhaling the dust in the enclosed power supplies with fans.

 

b. Adopting the semi-potted design to improve the reliability of the power supply in a high-humidity and other harsh environments, which is better than the one with conformal coating on each side.

 

c. Within 70℃, altitude 2000m natural air cooling environment, 3-year warranty;

Within 50℃, altitude 5000m natural air cooling environment, 5-year warranty.

 

d. Output short circuit, over-current, over-voltage, over-temperature protection

e. Leakage current < 0.5mA/240VAC.

f. Work without fan at full load

g. 150% peak load output for 1 second
